Hi clement,
Based on my experiences, if you post a team site content onto a public-facing website the visitor will need to log in when you click the team site links.
For SharePoint Online in Office 365 for professionals and small businesses there is only one site collection which is the public-facing website. The Team Site is also a sub-site under the public-facing website. You can create multiple sub-sites under the site collection. You can create the sub-site which is same level as the default Team Site from SharePoint Designer.
Basically, the users won’t have option to access Site Settings, whereas administrators will have this option in Site Actions.
I’d like to confirm the last question if you are asking why the document property you designed can’t be fully viewed from SharePoint Workspace. If yes, the SharePoint Workspace mainly provides an easy way to view/download documents store on the TeamSite. It will only retrieve the pre-design property of the document from the backend database. If you want to view the completed document property, you will require accessing the document library from web.
Thanks,
Kent Gu
